The polymer (trehalose) shape. At frame 3 is a fin-TSD followed by a normal TSD (because the step is too far for kaidan to work). It is fin-TSD at frame 11, followed by a polymer (fin-TSD + neo-TSD combo, i.e. trehalose). Explanation thanks to RandomTetris Noob, and fumen thanks to Larrytetris; further pages will be created on neo TSDs and Fins to explain these elements.

"It takes very few keystrokes to set each piece in place, and you can even take advantage of DAS/ARR repeat across pieces for the OIL." - Larrytetris.

"They are impractical and dangerous in modern multiplayer and will always remain an outside quirk of a blanket rule, in my book. The stack for them is not flat, and for the number of lines taken to do one (including the high overhang, which is I assume easy to get spiked on), their send-attack ratio is poor. With the number of pieces used, a normal t-spin double is nearly always better, and a tetris cleaner and less risky." - Paul676

The Godspin

This is a little too extravagant to be doing for any other purpose except to "look extravagant". However, it's a decent exercise in understanding tspin polymer mechanics.

Continuation into 4-Wide Combo

An Example

Godspin Setup Followed by Center 4-Wide

This setup works with nearly any bag: (TTL base)

When setting up Godspin in the center, make sure to only use two Z pieces in the stack, and the use the 3rd to create the floating blocks - any extra will cause stacking problems. Likewise, only use the first two T pieces in the TTJ base, save the 3rd for the first attack. If you have an early S in the 3rd bag, just place it on top of the S used on the side overhang, and wait for another I piece to fix the stack on the side:
